Fans have already enjoyed an early taste of ARTPOP, after Lady Gaga bowed to the pressure of hackers and has premiered the full version of her new single 'Applause'. Listen below.

Last week, her track 'Burqa' appeared online ahead of release. When asked by fans what she thought of the leak, she replied simply: "Please take these down as much as possible."

Alongside Elton John, Kings Of Leon and Justin Timberlake, Gaga is one of the biggest names on the 2013 iTunes festival line-up, which sees free gigs taking place throughout September at the North London venue.
